To all whom itmay concern.-

Be itknown that- I, WALTER J. KIDD, a subject of the Queen of Great Britain, residing at South Orange, in thecounty of Essex and State of New Jersey, have invented a new and useful Carbureting-Lamp, of which the following is a specification.

My invention appertains to that class of carbureting-lamps in'which heated gas is employed to vaporize a heavy hydrocarbon.

The objects of my invention are, first, t

ing lamp suitable for attachment to existing chandeliers, gas-drops, or brackets; secondly, to provide a suitable construction both for the heatin' of the asiau'cl the regulation of theexten't of carburation of the same; thirdly,

to provide a convenient and centrally-located shadesupport.

Hitherto Where heated gas has been made to impinge on the surface of naphthalene or other heavy hydrocarbon for the purpose of vaporizing the said hydrocarbon the gas has been raised to the required temperature either by the direct heat from the gas-flames coming in contact with the pipe or chamber in which the gas was heated or else the said pipe or chamber has been heated 'by a body of hot air retained around-it by a heat-arrester or casing, there being a space between the casing and the pipe or chamber. A principal part of my invention consistsin-using conducted heat in place of the aforesaid direct heat or bath of hot air. I convey the heat from the gas-flames to the gas-heating pipe 'or'tube by means of a simpleheat conducting device, in the form of a laterally=projectin g plate having a close-fitting collar, su rrounding and in contact with the gas-inlet pipe, the lateral flange being located above the level of the gas-flames and adjacent thereto. By this means the devices for heating the gas can be much simplified and are also much less expensive. I

In the drawings, Figure 1 is a view, partly in section and partly in elevation, of'my improved apparatus. Fig 2 is a top viewof the laterally-projecting heating-plate.

In the drawings similar nuin'bersa refei' to similar parts.

in the casing 7.

The carburetin'g -lamp is attached by coup? ling 2 to the outlet 1 of an ordinary gas-fire ture; The gas-channel is continued along the bent tube 3, elbow 4, and verticaldescending tube or gas-heating pipe 5, which latter passes into the upperpart of the shell 6 containingthe naphthalene. Around the lower part of the vertical pipe 5 is rigidly and permanently attacheda casing '7. This casing has an annularv chamber 8 surrounding the gas-tube 5 and communicates both with the carburetingvessel and with the burner-tip 9. The shell 6 is detachablysuspended at its neck 10 to the casing 7 by ascrew inlet or opening 11, which engages the external" serewthread 12 on the casing 7. When theshell is sc'rewed into position, it is made gas-tight by coming in contact with asbestos washer 13, which fits into a recess The neck or opening atthe top of the carbureting vessel 6 thus serves as a filling-orifice for replenishing the shell with naphthalene, and the she'llbeing detachable in the manner described, may be conveniently removed for thepurpose of refilling without disturbing the fixed upper portion; Located at the upper part of the tube 5 and above the gas-flame (indicated by dotted lines at l llisa horizontal flange or heat-conducting plate 15, which is preferablya light iron casting. A plan or top view of this plate is shown in Fig. 2. It will be-noticed that in the formshown in'fthe drawings the plate 'passes outside the gas-tube 5, being fitted thereon by a close-fitting collar 16 in continuone contact with the tube '5 for the purpose of more readily conducting and distributing the heat over the surface of the gasheating tube. The heat-conducting plat-e projects'on' one side laterally and horizontally above the flame. At the edge farthest from the tube 5 the plate has a small flange 17, turning down ward. This heatconducting plate can be raisedor lowered to any desired position on the tube 5 and can befirred where required by 5 means of a set-screw 18, which passes through the collar 16. In the case of a single gas-jet I prefer the'construction shownin the drawings, in which it will be noticed that the heatconducting plat-e projects on one side only of port 19 rises from the elbow 4; It is rigidly connected with the elbow and is preferably cast integral therewith. It supports a ring 20, to which may be brazed or otherwise secured the ends of the shade-holder rods orwires 21,

which clamp the lip of the shade 22. One of the shade-holderarmsor wires isprovided with a set-screw 23 to properly secure the shade. The shade-holder, with its ring 20, can be readily taken 01f the shade-holder support 19. Aloose thread may engage the two parts, or, as shown in the drawings, the ver- 0. The gas-flame highly heats the laterally-v the carbureting vessel 6, and thence through the annular outlet-channel 8 to theburner-tip projecting heat-conducting plate 15, which, being inv close contact with the tube 5 at the collar 16, conducts the heat very effectively to the gas-tube 5. Some heat is also given to tube 5 by radiation from the flame. The incoming gas, passing through the highly-heated tube 5, becomes heated in turn and after melting and vaporizing the naphthalene contained in the shell 6 passes, with the vapor therefrom, to the burner-tip, giving to the flame the enrichment due to the hydrocarbon. The laterally-projecting plate may be of any convenient shape and may be inclined more or less from the horizontal; but I prefer to employ a horizontal plate provided with a slight flange, as shown in the drawings. When the heat-conducting plate is raised to a higher point above the flame, it receives less heat therefrom, and thus by raising or lowering the heat-conducting late the gas may be heated less or more. of generation ofn-aphthalene-vapor can be regulated.

In the construction herein describedthe laterally-projecting plate serves. the special purpose of conveying heat by conduction to the gas-heating tube, and thus raises the gas n this 'way tne'extent passing through said tube to a l1igh',teinpcrature to enable it to melt the hydrocarbon in the carbureting vessel. Itis thus a gas-heat ing device. ing around the heated pipe in that it does not retain a bath of hot air around the pipe. A.

shallow-horizontal heat'condnnting plate has an advantage over a longer bell-shaped cus ing in'that it cnablestho gas heating-tube to be shorter and thus makes the small law-p morebompa'rit. "At tlfe same time the con structicn is less expensive.

tube 3 enables the shade to be both oen trally located and also outside of the gas-channels forming part of the lamp. In this way an exceedingly simple, symmetrical, and com pact construction of lamp is secured.

What I claim as my invention is- 1. Ina carbu-retlng-lam p, the combinatiim, of a carbureting vessel, a gas-burner, a vertical descending gas: inlet tube 5, located above the carbureting vessel, said inlet-tube. entering at the upper part of the vessehauu being rigidly attached toa burner-casing- '2,- support-ing the vessel; and a laterally-pro jecting flange or heat-conducting plate, lo cated around, and in contin uous contact with, the said'descending gas-inlet tube, at the collar'of'rsaid flange, and situated above andin proximityto the gas-burner, and below the upper end- .of the vertical descending inlet pipe 5, substantially as and for the purposes described. 1

2. In a carbureting-lamp, the combination, of a gas-burner; a vertical descending gas inlet tube 5, located above the carbureting vessel, and entering at the upper part thereof; a lateraily-projecting flange located around, and in continuous contact with, the said descending inlet tube, at the collar of said flange, and situated above, and in proximity to, the gas-burner and below the upper portion of the vertical descending tube 5, said projecting flange being vertically adjustable upon the gas-heating pipe, by a sliding movein the presence of two witnesses.
